Abstract To select refractory major ingredients of saggers for the calcination of Li‐ion battery cathode Li(Ni x Co y Mn z )O 2 ( LNCM ) materials, interactions between MgO‐based refractories, ie, magnesium aluminate (MgAl 2 O 4 ) spinel, forsterite (2MgO·SiO 2 ), and cordierite (2MgO·2Al 2 O 3 ·5SiO 2 ), and LNCM materials were compared respectively via refractory‐ LNCM precursor cylinder testing in lab‐scale. The phase composition and microstructure evolution of the calcined cylinders were characterized and resulted in comprehensive understanding and comparing of degradation of the MgO‐based refractories. The results reveal that cordierite is severely corroded, whereas magnesium‐aluminate spinel reacts little with LNCM materials. Refractories contain both SiO 2 and Al 2 O 3 with a higher SiO 2 level will suffer a more serious corrosion contacting with LNCM materials.
